Okay, let’s calculate this. Deborah has skills like land use planning, sustainability, and urban design, which are in demand. She has experience in landscape design and has worked with the City of Philadelphia. Location is Philadelphia, PA, which is a mid-sized city. According to national averages, urban planners with similar skills and experience can charge around $50-$100 per hour. Considering her experience and skills, I'll estimate around $75 per hour.
